Idk what it means by "missing base"
I think the base is the line with an arrow with no dimension. (changed )
We have a trapezoid with a height of 3 and one base of 7.2
To find the missing base , B :
17.175 = (1/2) (3) (7.2 + B)
17.175 = (3/2) ( 7.2 + B)
17.175 (2/3) - 7.2 = B = 4.5 (ft)
Thanks!
Hello, Guest! Are you gonna thank me too although my answer is different?
